Lebar Bedengan untuk Genangan dalam Parit pada Tanaman Kedelai

Abstract

In saturated soil culture the width of the be& were recommended between 1 m and 2 m, which require more labor to dig the furrows. An experiment was done to study the effect of the width of beds and to determine the optimal bed's width. The experiment was done on Regosol soil in Sleman Regency, Yogvakarta using Randomized Complete Blocked Design with three blocks. The treatments were Jood irrigation as control and saturated soil culture with 1, 2, 3 and 4 m wide of beds. Observations were done on soil moisture, physiological processes, growth and yield of soybean. The result of the experiment showed that saturated soil culture stabilized the soil moisture around field capacily, increased physiological processes, growth of the plant and increased the seed yield 81 %Ji.om 1.17 t ha-' up to 2.12 t ha-'. mere was no significant different on the effect of width of the beds, therefore 3-4 m bed's width was recommended.
